Brief summary
The purpose of this study was to determine whether early intervention with subcutaneous (s.c.) secukinumab 300 mg in patients with new-onset moderate to severe plaque psoriasis may lead to prolonged symptom-free periods by preventing reactivation of old lesions or ultimately totally hindering the occurrence of new lesions, i.e., changing the natural course of the disease (Main Study).
Detailed description
This was and open label, parallel group, multicenter, randomized study with 3 clinical periods: Screening period, Treatment period, and Follow-up period. The design consisted of the Main Study and a Mechanistic Sub study: 1. The Main Study had 2-treatment-arm secukinumab and nb-UVB). 2. The Mechanistic Sub-study had 4 arms treated with secukinumab and one arm with nb-UVB arm. The outcome measures were all exploratory, i.e. no results presented. Not all participants of the Mechanistic Sub-study participated in the Main Study, these participants are only reported for the safety analyses, but not for the primary and secondary outcome measures.
Interventions
Secukinumab (AIN457) 300 mg was administered in an open-label fashion according to label as 2 s.c. injections of secukinumab 150 mg (1-mL liquid formulation in a pre-filled syringe). Each 300-mg dose was provided as 2 pre-filled syringes of 150-mg secukinumab in a single box. Each syringe was labeled as AIN457 150 mg/1 mL.
Narrow-band UVB applied in 1 or 2 cycles, each comprising a period of 12 weeks with 2 to 3 treatment sessions per week totaling 24 to 36 sessions per cycle. The application was performed according to the investigational site's protocol, taking into account the patient's skin type. A maximum dose of 3 J/cm2 on the body and 1 J/cm2 on the face was recommended

Episodes of mild psoriasis, which occurred at least 3 years before screening and resolved spontaneously within 6 months will be accepted. * Chronic plaque psoriasis with appearance of the first psoriasis symptoms 5 years or longer and intolerance or inadequate response to phototherapy or any systemic treatment including biologicals, except for IL-17A inhibitors (Arm C1 and Arm C2). * Moderate to severe plaque psoriasis defined at screening and baseline by PASI \>= 10, and body surface area (BSA) \>= 10%, and IGA mod 2011 \>= 3. Key
Exclusion criteria
* Forms of psoriasis other than plaque-type (e.g., pustular, erythrodermic, guttate, light sensitive, and drug induced). * Ongoing use of prohibited treatments. * Previous treatment with phototherapy or any systemic treatment. * Pregnant or nursing (lactating) women. * Women of childbearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using effective methods of contraception during the Treatment period or longer if required by locally approved prescribing information (e.g., 20 weeks in the EU and countries where applicable for secukinumab).
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Who Achieved Pain Assessment Severity Index (PASI) 90 at Week 52. | Baseline, Week 52 | The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of Body Surface Area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI composite score varies in increments of 0.1 and range from 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. PASI 90 response is a binary measure defined as at least a 90% improvement in PASI score at Week 52, relative to baseline PASI score. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants Who Achieved PASI 90 at Week 104 | Baseline, Week 104 | The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of Body Surface Area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI composite score varies in increments of 0.1 and range from 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. PASI 90 response is a binary measure defined as at least a 90% improvement in PASI score at Week 104, relative to baseline PASI score. |
| Number of Participants With IGA Mod 2011 0/1 Response at Week 52 | Baseline, Week 52 | Investigators assessed the disease using the validated Investigator Global Assessment (IGA) mod 2011 and rated the disease from a score of 0 (clear skin) to 4 (severe disease). Response is defined as a score of 0 or 1 at Week 52. |

Outcome results
Number of Participants Who Achieved Pain Assessment Severity Index (PASI) 90 at Week 52.
The PASI quantifies the severity of a participant's psoriasis based on both lesion severity and the percent of Body Surface Area (BSA) affected. PASI is a composite scoring by the investigator of degree of erythema, induration, and scaling (each scored separately) for each of 4 body regions (head and neck, upper limbs, trunk \[including axillae and groin\], and lower limbs \[including buttocks\]), with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. The PASI composite score varies in increments of 0.1 and range from 0 (no disease) to 72 (maximal disease), with higher scores representing greater severity of psoriasis. PASI 90 response is a binary measure defined as at least a 90% improvement in PASI score at Week 52, relative to baseline PASI score.
